It lives.

Blew away the cobwebs, found some cables and powered it up. Then not much happened for a long time. A few internet searches later and lots of stories of super fixes and horror stories of other situations. Must remember to store the cables and their parent devices together in the future. Anyhow, power source from Asia used and the machine sprung into live. Quickly followed by logging off and note to self to buy new power thingy tomorrow. Whilst not forgetting to blip.
